Chapter 5. Equations of Mass Transfer

Learning Objectives

After completing this chapter, you will be able to:

  • Derive differential equations for mass transfer in Cartesian coordinates in flux form.

  • Express these relationships in vector form so that they can be used for any coordinate system.

  • Define the mixture velocity and the diffusion flux.

  • Examine some properties of the diffusion flux.

  • State some forms of Fick’s law for binary systems depending on the frame of reference used.

  • Derive the differential equation for the concentration field by combining the equation in the flux form with Fick’s law.

  • State the boundary conditions for many standard cases.

  • Show how averaging of differential models leads to mesoscopic and macroscopic models, and describe ...
